Specification of Letters Patent.

Patented June 1906.

Application filed February 16, 1906. Serial No. 301,340.

To all whom it may concern:

Be it known that I, J ACOB ScHMITT, a citizen of the United States, residing at Newark, in the county of Essex and State of New J ersey, have invented certain new and useful Improvements in Gas-Cocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

The invention relates to an attachment to be placed upon gas-fixtures that encircles the larger part of the fixture, so as to cover it, and thereby add to the symmetry of the fixture, and is designed particularly to prevent accidental turning on of the gas after it has been once turned off without raising the device that does the locking.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side view of the ordinary gas jet or fixture provided with my new locking attachment. Fig. 2is a section on line 2 2 in Fig. 1, but being modified by the omission of an actuating-spring Fig. 3 is a bottom view of the locking device separate from a fixture.

In the drawings, 10indicates the usual form of fixture having the reduced portions 10 on either side of the central part of the valve. Arranged to fit around these reduced portions is a cup-shaped locking device 12 with a cut-away portion 13, so that it can ride up and down. The device is raised when it is desired to turn on the gas, and when it is in that position the handpiece 11 of the valve is at right angles to a slot or slots 14, cut radially in a perforation 12. The gas can be turned down or up; but When it is closed entirely off the locking-piece 12 snaps down, being forced by the spring 15, and the slots 14 securely hold the handpiece of the valve in its locked place. The locking-piece 12 can be raised by the finger without turning on the gas, and the two movements can be combined so as not to make the operation of the device awkward. The locking-piece 12 can also be raised by any ordinary gas-lighter if the gas-jet is out of reach.

It will be seen that the device is very cheap to make, easy to put on any fixture, and cannot fail to act by gravity, or is spring-actuated, as in Fig. 1.

Having thus described the invention, what I claim as new is A lock for gas-cocks comprising a cupshaped member to surround the cock, having a central perforation in the bottom, and cutaway portions at opposed points in its walls, said member also having opposed slots in the edges of the central perforation to lock the gas-cock, and a spring within the cup-shaped member to force the bottom of the member in (iontact with the finger-piece of the gascoc r.

In testimony that I claim the foregoing I have hereunto set my hand this 6th day of February, 1906.
